The present invention pertains in general to covers for culinary vesselsand more particularly to self-basting covers for roasting pans and thelike ofthe same general type as that disclosed in my Patent No.1,598,222,

dated August 31, 1926; the subject matter of the present applicationbeing in part divisional of this patent. j

In accordance with the general features of my present invention Iprovide a cover equipped with means for promoting the condensation ofthe vaporized juices of the roast, for directing and distributing thejuices evenly over the roast, for allowing the steam to escape therebyproducing a solution of highly condensated grease which is so essentialto a thorough browning of the roast, and

which is self-basting to such an extent that the attention of a personwill not be required.

It is of course, to be understood that although I shall describe myinvention as being particularlyv useful in connection with roasters, theinvention is not to be thus limited but only in so far as dened by theappended claims. f

Other objects and advantages of myv invention will more fully appearfrom the'folllowing detailed description taken in connection with theaccompanying drawing which illustrates several embodiments therel Therim 11 and the flange 12 are adapted f to cooperate with the roastersuch as that disclosed in my Patent 1,598,221.

The dome-shaped cover 10 is preferably of a semi-spherical form andincludes a pair of annular troughs y13 and 14. The body of the cover 10may be pressed from suitable -metallic sheet and is preferably a punchpress product.` The cover 10y is equippedl with a handle '15 which takesthe form of f a knob mounted approximately centrally of" i f the coverand held in place by means of `a screw 16 which passes through anaperture 17 in the Vcover and is threaded into the knob.

A washer 18 is lpreferably placed between the head of the screw andtheinterior of thecovenV w The vtrough 18 is defined by'a downwardlyextending ridge-like projection 19 which has an arcuate cross section.Similarly, the annular trough 14 is defined by a downwardly extendingannular ridge-likeprojection 20 which also has `an arcuate, crosssection.

These two projections 19 and 2O are prefer-L ably disposed on cover 10.e

It will b'e'notedfroin Figs, land 2 thaty each of the projections 19and'20 isequipped with a plurality of apertures21 spaced .a

` the l underside rof the given distance' fromeachother.V VFurther- Imore, I preferably make each of'these apertures of a nozzle-like ortapering shape, the purpose of which will be more fully dcscrib'edhereinafter; Q

'The taperedapertures'21 serve as a meansV for permitting thefsteam topassk through v j the cov/er.V Also, the apertures form air vents forthe' interior ofthe vessel andfse'rve to prevent the boiling over ofthecontents within the associated, roaster. Furthermore,` theV`apertures promote condensation of the vaporized juices of the meatV4 orother food lbeing roasted and assistvthe downwardly depending ridges 19and V2O in collecting and distributing the condensate uniformly over theroast. vEach aperture or opening is tapered and its size is independentof the size of the associated projection or ridge. The'advantage of thisconstruction is that it enables a relatively large projection to be usedwithoutincreasing the sizeof the openingi21. It Will be evident thatbyproviding relatively large annular ridgesor projections a greatercondensingvsurface is afforded the vapors within` the associatedvessel.V Moreover, by providing relatively small openings only part ofthe vapors are allowed to escape. Also, a part of these escaping vaporssubstantially' uniform self-basting action will condense in the troughs13 .and 14 and over the contents of the roaster.

i By tapering the opening 21 I lind that I OLAF TOLLAGSEN. 70

canv increase the condensing surface of the ridges or projections. Also,the tapered openings in reality serve as pockets in which the condensateis adapted to accumulate.

Now I desire it understood-that although Y 1 75 I have illustrated anddescribed in detail the 'i preferred embodiment of my invention,.theinvention is not to be thus limited but only in so far as defined by thescope vand spirit of the appended claims. 'i
